You can travel by train with up to two dogs, cats and other small animals free of charge, providing staff and passengers are not inconvenienced or endangered. You will incur a charge, on top of your train fare, if you need to travel with more than the maximum number of dogs, cats and other small animals.
Dogs must be kept on a lead at all times, or otherwise kept in an enclosed pet carrier (as must cats, birds and small animals) in which they can lie down comfortably. Animals and pet carriers are not permitted on train seats.
If a passenger complains about the presence of your animal, it must be moved to another carriage or placed inside the guard's van / luggage van (where available). Unless they are already in an enclosed carrier or basket, dogs carried in the guards' van / luggage van must be secured with collar and chain and properly muzzled.
The carriage Steward may permit blind persons' guide dogs or deaf persons' assistance dogs into the restaurant carriage, but no other animals are permitted to travel in this part of the train.
On Sleeper services, blind or deaf persons' assistance dogs are permitted at no extra cost, providing the booking is in single-cabin accommodation. ScotRail offers able-bodied passengers in Sleeper services the opportunity to travel with dogs although there are some conditions
Livestock eg. sheep, pigs and goats may not be carried on UK trains.
